Inlet rocker box
Inlet-side rocker box for the cylinder head, shown in 1971 TR6R, TR6C, and T120R parts book listings.
This is the inlet rocker box, part number 71-2350, also listed under the older E12350 number. It sits up top on the cylinder head where the inlet rockers pivot and work the inlet valves, and it's shown in the parts book alongside the cylinder block and head assemblies for the TR6R, TR6C, and T120R.

The rocker box is a shell that bolts down over the rocker gear on that side of the head, keeping oil in and dirt out while giving the rockers a solid place to pivot from. On these engines the inlet and exhaust rocker boxes are separate castings, so make sure you're ordering the inlet side and not the exhaust box when you're sorting out top end parts.
The catalog record ties this one to 1971 production. If your head or rocker gear is from a different year, it's worth checking dimensions against what you've got before you order, since small changes in castings over the years aren't always obvious just from a part number.
